Puparium length: 812 ± 82 [892]; maximum width (between level of T2/T3 suture and A1): 607 ± 62 [684]; length/maximum width: 1.3 ± 0.1 [1.3]; width at level of anterior margin of operculum: 366 ± 53 [441]; maximum width/width at anterior margin of operculum: 1.7 ± 0.1 [1.7]; deflexed submargin/body radius: 0.6 ± 0.1 [0.6]; Ce setae: 7 ± 1.7 [missing]; T2 setae: 13 ± 4 [12]; T3 setae: 15 ± 4 [17]; dorsal A8 setae: 99 ± 18 [117]; caudal setae: 52 ± 8 [46]; anterior marginal setae: none visible; posterior marginal setae: 21 ± 5 [not visible]; ventral A8 setae: 27 ± 3 [29]; VO ring length: 68 ± 5 [71]; VO ring width: 92 ± 25 [90]; VO ring length/width: 0.8 ± 0.1 [0.8]; caudal seta/VO ring length: 0.7 ± 0.1 [0.6]; caudal seta/operculum length: 1.3 ± 0.2 [1.1]; VO length: 42 ± 3 [43]; VO width: 45 ± 4 [49]; VO length/width: 0.9 ± 0.1 [0.9]; operculum length: 38 ± 3 [44]; operculum/VO length: 0.9 ± 0.1 [1] (see Table 1 for ranges). Similar species . It resembles T. anahuac Carapia-Ruiz & Sánchez-Flores in Carapia-Ruiz et al ., 2018 described from Mexico on Quercus sp. by its U-shaped transverse molting suture ending before submargin and dorsal reticulation pattern. It shares the combination of a rounded-oval puparium lacking a caudal protuberance, presence of eyespots, Ce setae, large rounded tubercles on lateral areas of dorsal disc, TMS not reaching apparent margin, and hosts with T. abnormis and T. nevadensis . Diagnosis . It differs from T. anahuac , T. mexicana , and T. xalapensis Sánchez-Flores et al. 2018 , all of which also occur on Quercus (characters for the other species in square brackets, those for T. anahuac and T. xalapensis taken from Carapia-Ruiz et al . 2018 and Sánchez-Flores et al. 2018 respectively), by puparium rounded oval lacking a caudal protuberance ( Figs 43 , 48, 49 ) [puparium elliptical oval with a caudal protuberance; Figs 142 , 143 , 149, 150 ], dorsal A8 setae longer than caudal setae ( Figs 48, 49 ) [dorsal A8 setae shorter than caudal setae; Table 1 ], and venter extensively covered with spinulae ( Fig. 47 ) [smooth except for wide irregular band of spinules medial to leg bases and around mouthparts; Fig. 147 ]. It further differs from T. anahuac and T. xalapensis by presence of Ce, T2, and T3 setae ( Figs 43 , 44 ) [absent] and VO ring subtriangular with each anterior corner partially separated from remainder of ring, not forming entirely independent protuberances ( Figs 43 , 48 ) [VO ring suboval with anterior corners not separated from remainder of ring in T. anahuac ; with ear-like promontory on each anterior corner separated from remainder of ring forming entirely independent protuberances in T. xalapensis ]. Other differences from T. anahuac include its wide marginal ring ( Fig. 4 ) of curly wax [small ring], shorter (about 40–70 µm) caudal setae [about 90 µm], and smaller (length 700–970, width 490–690) puparium size [length 1,120, width 860]. It also differs from T. mexicana and T. xalapensis by its U-shaped ( Figs 43 , 44 ) transverse molting suture [W-shaped; Fig. 143 , 144 ], dorsal setae of A8 ( Fig. 48 ) arising anterior to level of anterior margin of operculum [at that level or posterior to it; Fig. 149 ], and bases of caudal setae close together, within level of operculum lateral margins ( Fig. 49 ) [more widely separated, outside level of lateral margins of VO ring; Figs 143 , 150 ]. It can be further distinguished from T. xalapensis by mediodorsal area of T2 and T3 devoid of large rounded tubercles ( Figs 43 , 44 ) [with tubercles], one row of squarish tubercles along anterior margin of A1–A7 ( Figs 43 , 46 ) [two rows of subcircular reticulation along anterior margin of each abdominal segment], and operculum surface lacking a 'W' shaped crest ( Fig. 48 ) [with a 'W' shaped crest]. Tetralicia agrifoliae can be recognized from T. abnormis and T. nevadensis (characters for the latter two in square brackets) by its wide lateral fringe of filamentous wax ( Fig. 4 ) [narrow lateral fringe, Fig. 1 , or without noticeable wax formation respectively], TMS approximately 'U' shaped, with transverse section almost straight and distal ends bent at almost 90 degrees ( Figs 43 , 44 ) ['W' shaped, with transverse section bent caudally and distal ends bent at about 45 degrees; Figs 29 , 151–153]. It further differs from T. abnormis by tubercles bordering longitudinal molting suture extending from TMS to level of mouthparts ( Figs 43 , 44 ) [tubercles bordering longitudinal molting suture extending from suture between T2/T3 to submarginal area; Figs 29 , 30 ], lacking mediolateral depressions on head, T2, T3, and abdomen ( Figs 43 , 44, 46 ) [with mediolateral depressions on head, T2, T3 and abdomen; Figs 29 , 30, 34 ], and lateral areas of dorsal disc and submargin with large rounded tubercles forming a reticulate pattern ( Figs 43 , 44, 46, 48 ) [lacking large tubercles; Figs 29–31, 34 ], and from T. nevadensis by eyespots oval ( Figs 43 , 44 ) [slit-like, narrowly transverse] and bases of caudal setae close together, within level of operculum lateral margins ( Fig. 49 ) [widely separated, outside level of lateral margins of VO ring]. Remarks . Dooley et al. (2010: 10 , 14) mentioned an undescribed species from Nevada (as Aleuropleurocelus sp. #2) also found on Quercus sp. with an oval puparium lacking a caudal protuberance and with oval eyespots. This short characterization could apply to T. agrifoliae , but examination of puparia of Aleuropleurocelus sp. #2 at USNM revealed that it represents a different species lacking cephalic and thoracic setae (Ian Stocks pers. comm .). Distribution . Southern California (Los Angeles , Riverside, and San Diego Counties).
